20 Claims.

This invention relates to apparatus for assemarranged with a screwthread to co-operate with the thread about the opening of a receptacleto which the closure is to be applied, the liningsV or sealing padsbeing secured in the caps under the tension of the linings themselvesand the obstruction of the thread of the caps.

It is the primary object of the invention to provide an apparatus forassembling sealing pads or linings in a plurality of closure caps at thesame time without materially increasing the dimensions thereof over thedimensions of the present typeof apparatus and increasing the capacty ofthe apparatus by assembling twice the number of caps within a givenperiod of time.

Another object of the invention is to provide an apparatus wherein aplurality of linings may be simultaneously severed or stamped from asingle web of lining material, thereby greatly reducing the amount ofwaste lining material.

A further object of the invention is to provide means to direct closurecaps from a conveyer transporting the caps from the forming or screwthreading apparatus to a plurality of conveyers for equally distributingthe caps to the assembling devices of the apparatus.

It is another object of the invention to provide controllable power ordriving means for the apparatus whereby the closure caps are fed to theapparatus before the assembling devices are placed in operation, therebynot only reducing the amount of power consumed in operating theapparatus, but also assuring the presence of closure caps at theassembling devices when set in operation.

It is a further object of the invention to adapt the apparatus forassembling dierent size caps by removably mounting parts of theassembling devices on the apparatus to permit the ready replacement ofsaid parts by parts of the desired y size and by having the remaining,parts readily adjustable to accommodate different size caps. It is astill further object of the invention to provide means to disconnect theassembling' devices from the power means and simultaneously stop theactuation of said devices.

A still further object of the invention is to provide means to stop theactuation of the assembling devices should there not be a cap in frontof an assembling device.

Other objects and advantages Will hereinafter appear.

In carrying out the invention there is provided pairs of parallel railsfor lsupporting the caps relative to the assembling devices and to whichrails the caps are delivered from a cap forming yor threading apparatus-by a conveyer belt trav- 5 eling in longitudinal alinement with therails and continuously transporting caps relative to means reciprocatorytransversely of said belt to direct the caps from the belt to a pair ofconveyer belts traveling along the opposite longitudinal edges of thefirst conveyer and the outer edges of the supporting rails. The pair ofconveyers continuously transport the caps thereon relative to slidesmounted at the outer marginal portions of the pair of conveyers andreciprocatory transversely across said conveyers to the outer mar;-ginal portions oi' the cap supporting rails to transfer the caps fromthe conveyers to the rails relative to projections extended above therails from a pair of chains traveling below and in alinement with thepairs of supporting rails and intermittently actuated to permit thepositioning of caps by the slides in front of a pair of projections tobe engaged and moved by said projections along the supporting railsthrough the actuation of the chains. The caps are transported along therails by the chain fingers relative to pairs of punch and die mechanismsmounted above the supporting rails, one pair of punch and die mechanismsbeing arranged in sequence to the other relative to the movement of thecaps along the supporting rails with a punch and die of each pair ofsuch mechanisms positioned above a pair of the supporting rails. Thepunches are actuated during the periods of rest of the chains to severlining disks from a web of lining material fed to each pair of punch anddie mechanisms and the severed disksv assembled in the caps by a plungercarried by each of the punches and actuated in successive sequence tothe severing of the disks. The feeding of the web to each pair of punchand die mechanisms is controlled bythe caps on the rails before the capsare positioned in alinement with the punch and die mechanisms, theabsence of a cap on either pair of supporting rails rendering the webfeeding means inactive to feed the web to the pair of punch and diemechanisms in front of which punch and die there is no cap, andtherefore no linings will be cut from the web by said punch and die. Thelining webs fed to the different pairs of punch and die mechanisms maybe of the same material or of dierent materials to form a sealing padand a protective lining for the pad. 'I'he caps having the assembledlinings therein are discharged from the apparatus by the travel of thecaps along the supporting rails, the cap engaging projections of thechains being disengaged from the caps through the travel of the chainsin an arcuate path adiacent the discharge ends of the supporting rails.

In the embodiment of the invention illustrated in the drawings theoperative parts -are mounted upon a` suitable framework comprising a bedor table B supported at the opposite ends upon 20 lstandards S, andareactuated from a drive shaft I1 having two crank portions I8 intermediatethe' ends, for a purpose to be hereinafter described, and. at the endsrotatably mounted in hangers I9 suspended from they opposite sides ofthe bed 25 B. One of the shaft ends extends beyond its hanger and hasloosely mounted thereon a power or drive wheel 20 having two rows ofsprocket teeth 2l on the periphery thereof, said wheel being retained onthe shaft against lateral move- 30 ment by an annular enlargement 22 ofthe shaft in spaced relation to the end thereof and a collar 23releasably secured on the end of the shaft at the outer side of thewheel. The drive wheel is positively actuated from an electric motor Mby 35 a pair of sprocket chains 24 engaged by the sprocket teeth 2l ofthe drive wheel and passing around a pair of sprocket wheels 25 fixed onthe shaft of motor M. The motor is mounted on a shelf 26 extendinglaterally from a standard S 40 and the motor is connected to a source ofelectricity through va rheostat enclosed in a box 21 by which the speedof the motor may be regu-- lated. Y

The drive .wheel 20 is releasably connected to-45 the drive shaft I1 bya key 28 slidably mounted in a keyway in the vshaft and yieldingly urgedthrough an opening'in the annular enlargement 22 toward the hub of drivewheel 20 by a spring 29 vengaged in a recess in the ykey and abuttingthe 50 end of the keyway in the shaft, as shown in Figure 8, the freeend of the key engaging a notch 30 in the end of the hub of the drivewheel having a declined portion 3l leading to said notch to facilitatethe engagement of the key with the notch during the rotation of thedrive wheel. It will readily be seen that the drive wheel is normallyconnected to the drive shaft by the yield ing force of the spring 29,and the shaft I1 is disconnected from the drive wheel 2II by an arm 0032 pivotally mounted at one end on a pintle 32' fixed in a hanger I9 andthefopposite end movable toward and away from the key 28 and arrangedwith a block 33 flxed to said end having a longitudinal cam edgeextending from one face to the opposite face, as at 34 in Figure 14, toengage a recess in the free lateral edge of key 28 and adapted to movesaid key away from the drive wheel against the force of spring 29 by themovement of the arm toward the key so that at the end of said movementof the arm the key will befully disengaged from the wheel notch 30.`

Upon the releasel of the. drive wheel from the drive shaft, the driveshaft will continue to ro- I tate throughits own momentum with theresult that the operative parts of the apparatus will continue tofunction contrary to the intent of the operator and cause. damage to thereceptacle closure caps and waste of the lining material.

To prevent this the drive shaft .is normally held against rotation bybrake imeans, consisting of a band of flexible material having a liningon 'the inner surface, as at 35 in Figure 14, the band being engagedabout the annular enlargement 22 which serves as a brake drum, theopposite end portions of the band being extended laterally and inparallel relation to each other with one end attached to a post 31 fixedin and projecting from the adjacent hanger I9 and the opposite end freeand yieldingly. urged toward the fixed end by a spring 38 coiled about aheaded rod 39 loosely en- .gaged in alined perforations in both endportions of the band with the head abutting the free end and the springconfined between the fixed end and a washer 49 adjustably retained onthe rod by lock nuts 4I. The portion of the band extending from thefixed end is prevented from being moved by the spring beyond apredetermined point by a pin 42 extended from the hanger abutting theband on the side of rod 39 opposite the post 31, so that the force ofthe spring will only move the free end toward the i'lxed end, themovement of the free, end away from the fixed end swinging the entireband about the post 31 away from pin 42 and free the band from the drum22, thereby permitting the free rotation of the shaft I1.

Means are provided to simultaneously actuate the brake band to releasingposition.and arm 32 away from key 28 to permit said key to connect thedrive shaft to the drive wheel, and comprises a lever 43 having atriangular opening 44 in an enlarged portion intermediate the endsthereof extending in an axis oblique to the vertical and engaged upon aroller 45 carried by a stud xed in a hanger I9, the roller beingmaintained in predetermined positions in the opening by a coiled spring46 attached at one end to the stud carrying roller and the opposite endattached to a pin 41 projecting laterally from the arm 32, so that theside of the opening nearest the pin 41 will be yieldingly engaged by theroller 45. The end of lever 43 carrying the pin 41 is connected, as bysaid pin, to the arm 32 intermediate the ends of said arm, and the lever43 being loosely connected to the free or movable end of the brake bandby a link 48 pivoted at one end to the brake band and having a slot 49in the opposite endportion loosely engaged on a pin 50 fixed in andextended laterally from the lever adjacent the side of the openingopposite to the side normally engaged by the roller 45. The lever 43 isactuated by a manipulating lever 5| connected to the end of the leveropposite to the end connected to arm 32 by a rod 52 pivotally connectedto the respective levers whereby the levers will have correspondingmovements in an upward and downward direction. In the downward movementof the levers the roller 45 will engage the uppermost portion of theopening 44 thereby moving the lever 43 in a lateral direction andcausing the pin 50 to move from the upper end to the opposite end of theslot 49 in and move link 48 about its pivotal connection with the brakeband without imparting movement to the brake band, said brake bandremaining in its braking position under the force of spring 38, saiddownward movement of the levers moving the arm 32 toward and actuatingthe key 28 out of engagement with the wheel notch 30, as clearly shownin Figurevl-i. The movement of levers 43, 5I in an upward direction thelevers, which movement will actuate the arm 82 away from the key 25 andt the key to move toward and engage the wheel notch 35 and 5' connectthe drive wheel to the drive shaft under the influence of spring 29. Theupward movement of the lever 43 simultaneously with said latter movementof the arm 32 will move the pin 55 along slot 49 into engagement withthe upper end 10 of the slot, the continued upward movement of lev'er 43lifting the link 48 and moving the brake band 35 away from the brakedrum, as shown in dot and dash lines in Figure 14, thereby permittingthe free rotation of the shaft Il and the actul5 ation of said shaft bythe drive wheel 20. The lowerend portion of the side of the opening 44has an offset, as at 53, forming an indent in which the roller 45 isnormally retained-against accidental movement during the operation ofthe ap- 20 paratus.

To prevent injury to the operator of the apparatus, the drive wheel 28,chains 24 and the sprockets 25 o1' the motor shaft, are covered by ashield 54 carried by the framework. 25

Caps C are fed to the apparatus from an apparatus, not shown, where thecaps are formed or arranged with screw threads, by an. endless conveyerbelt 55 of a Width to support a plurality of rows of caps, partiallyshown in Figures 2 and 6 30 to be supported and driven at one end by adrum 56 xed on a shaft 51 rotatably supported in bearings in brackets 58fixed to and extended from the end of the bed B adjacent the drive shaftl1. The caps fed by the belt 55 are sepa- 35 rated into two parallelrows in which position they are transported through the apparatus to thevarious assembling devices. This operation is accomplished by providingvibrating means to engage and direct the caps laterally of the conveyer40 55, said vibrating means being in the form of an arm 59 having atapered end arranged with a straight edge of exible material, as at 60,and at the opposite end fixedly mounted on a shaft 6I rotatable in abracket 62 supported on a 'raised 45 portion 62r of the bed B in spacedrelation to the drum 56, said shaft 6I being reciprocated to move theend 68 ofthe arm 59 transverselyof the belt 55 by an arm 63 fixed at oneend on shaft 6I below the bracket 62, the-opposite end carrying a roller50 54 yieldingly urged to engage a cam disk 61 fixed to th shaft 51 ofthe drum 56, by a spring 65 attached at the opposite ends to aprojection 66 of arm 59 and the bracket 52,A as clearly shown in Figure2. The reciprocation of the arm 59 will 55 direct the caps through thecontinuous travel of the conveyer 55 between pairs of guiding railsdiverging toward and past the marginal portions of the conveyer, saidrails comprising plates 68 having one end tapered with a straight sideand a 50 diverging side meeting a straight portion adjacent the oppositeend, as at 69, said opposite end-portions of the plate being adjustablymounted on a cross member 10 xedat the ends on the brackets 58 inhorizontal spaced relation to the conveyer 65 and arranged with pairs ofspaced slots 1I for the adjustable engagement of screws 12 threaded inthe plates 68 to permit adjustment of the plates laterally of theconveyer and toward and away from each other to position the inner sidesof the 70 vplates including the diverglng side portions 6,9

-v of the diverging 'parallel relation with the diverging side portionsof the plates,

the end portions of therails opposite to l.the ends fixed tothe crossmember extending in substantial alinement with fthe sides of theconveyer-'belt f 55 and'flxedly mounted on the 'raised portion 62'ofjthe be'd B, as at 14. The diverging portions of the plates 66 landthe rails 13 are arranged with an overhanging portion to extend over theperipheral portion of the caps, as shown'at 16 in Figure aroundsupported by pairs of drums 11, 16,

the drums"1 being xedly mounted on the opposite end portions-of a shaft16 rotatable in-bearings 60' ,on the top and at the opposite sides ofthe bed'B', and the drums v16v rotatably mounted on studs 6| slidablyengaged in slideways 62 in the outer ends of the brackets l56 andadiustably carried by lead screws 631loosely mounted in plates 6I 'fixed-to the ends of the brackets 56 spanning the openends of the slideways,said lead 'screws having threaded connectionl with the studs, the

ends of the screws extendingbeyond the plates 66 being arranged for theengagement `oi? an actuating tool, as at65, to take up any slack in thebelts 16. By this mounting it will be obvious that the belts 16 willextend parallelly of the opposite marginal portions of and in the sarneplane-as 'the conveyer 55, and that the guide plates 66 and rails 13extend over said pair of conveyers to guide the caps onto said conveyers16. The caps are further guided lon the conveyers 15 by rails 65v ofangular form in cross section adjustably carried by arms 81 by slot andscrew connections 66 to permit adjustment of the rails toward and away.

from'the rails 13 for the guiding of different size caps, the arms 61being loosely mounted on a rod 69 fixed to the raised portion 62' of thebed B.

so that the rails 66 may be raised away from the conveyers 16 to permitof inspection and removal of caps jammed on said conveyers, therails'being positioned in spaced relation to the conveyers in thelowered position `by the'ends of the arms 61 extended beyond the railsengaging raised portions of the bed B, as at 90 in Figure 2.

The conveyer belts* 55, 16 are simultaneously and continuously actuateddirectly from the drive wheel 20, independent of its relationship withthe drive shaft |1, by a sprocket chain 9| passed about an annularsprocket wheel 92 xed to the hub of the drive wheel, as clearly shown inFigure 8, and a sprocket wheel 93. fixed to an end'of aA stud shaft 94rotatable in a hanger 95 suspended from the bed B in alinement with abearing 60, and having a pinion 96 fixed thereto in spaced relation tothe sprocket wheel meshing with a pinion 91 fixed to an end of the shaft19 extended beyond bearing 60, as shown in Figure 6, whereby rotation isimparted to the drums 11 carrying the belts 16, this rotation beingimparted to shaft 51 of conveyer by a sprocket chain l96 engaged aboutsprocket wheel`99 fixed ,to the shaft 19 between a bearing and drum 11,and a sprocket wheel |00 fixed to the shaft 51, as shown in Figures 2'and 6. n

Ihe conveyers 16 transport the caps relative to means to transfer thecaps to pairs of supporting rails, comprising a pair of laterally spacedstrips |0| supported in horizontally spaced rela- `non from andcentrally of the top of the bed B by a series of posts |02, and a middleor center strip'l03'supported between thestrips |0| and from the bed byposts similar tothe posts |02 `section in Figure '7.

f Y aciarae and ofa widthto form with-th strips |0I two longitudinalslots or passageways |06, for a purpose to be hereinafter described.'I'he caps are supported by the rails in two rows relative to the slots|04 during the entire assemblingof i; liningsor pads therein, and saidrows of caps are guided between guide rails or strips ad- .iustablymounted on the outer marginal portions of the rails |0| by screwsthreaded in the rails |05 engaging slots extended transversely of the 1orails |0|, as shown at |06, and a rail |01'releasably mounted centrallyon the center rail |03 by screws, so that the rails |0|, |03 may supportdifferent size caps by adjusting the guide rails |05 laterally byloosening the screws in the 15 slot connections |06 and replacing thevcenter guide rail |01 with la rail of proper width. The

' cap supporting rails |0|, |06'extend from one conveyers 16 to thesupporting rails |0|, |06 and g5- vsaid terminating portions of theguide rails are arranged for the adjustable mounting of abutment plates|06 ofangular form having a slot |09 in one angle portion for the looseengagement of headed screws threaded into the rails |05, 30 whereby theother angle portions may have adjustment longitudinally of the conveyers16 to properly position different size caps on the conveyers 16relative-to the transferring means.

The means to transfer the caps from the con- 35 veyers 16 to thesupporting rails |0|, |06, comprises a pair of carrier blocks ||0(Figures 2 v and '1), each slidably mounted in a slideway of a pair ofslideways supported on opposite sides of the bed 4B outl of alinementwith each o other, as shown in' Figure 2, and each rblocl: slidablysupporting an ejector slide 2 having a slot ||3 engaged by a pin III xedin and extended frorn the block ||0 to permit of a limited longitudinalmovement of the'slide relative to 45 the block and impart movement ofthe blockto said slide toward and transversely of the vadjacent conveyer16, the return movement of the block away from the conveyer beingadjustably imparted to the slide through a set screw ||5 504 threadedin'a perforated lip ||6 of the slide to engage the block and secured inadjusted position by a lock nut |1, as clearly shown in cross The setscrew ||5 is yieldinglyvurged into engagement with the block by a 55spring ||6 attached at the ends to the pin ||6 and a pin ||9 fixed inand extended from the slide ||2 between the slot ||3 and lip H6. 'Iheblocks I0 are reciprocated simultaneously towardstheir respectiveconveyers 16 to engage the slides 60 ||2 with the caps abutting the.plates |06 and transfer said caps to the supporting rails |0|, |03, from-a shaft |20 rotatably supported in hangers |2| suspended from the bedB, and said shaft driven from the drive shaft |1` 'oy a sprocket g5chain |22 engaged about an annular sprocket wheel |23 fixed to driveshaftV |1 and a sprocket wheel |24 fixed to the end of the shaft |20ex-v tended beyond hanger |2|. The rotary movement of the shaft 20 istransformed into recip-` rocatory movement of the blocks ||0 by a pairoi' crank arms |25, each of said arms being pivotally connected at oneend to a collar |26 loosely engaged on a pin |21 projectingfrom theperipheral portion of'a disk |26 of a pair of disks fixed 75 beyond thehangers |2|, the opposite ends of the crank arms pivotally engaging inbifurcated connecting memLers |29 pivotally connected to an arm of belllevers |30 rotatably supported between hangers |3| suspended from theslidewaysthe other arms of the levers having the free ends bifurcated,as at |32 in Figure '7. and the bifurcations engaging pins |33- fixed inthe legs of bifurcated portions |34 dependingl from the carrier blocks0. By adjusting the set screws ||5 the# forward movement of the ejectorslides 2 is l.arie'd to properly position caps having `diiferentdiameters on the supporting rails |0|,

|03. The mounting of the slides ||2 are offset relative to each other sothat the slides will travel in a path directly below a guide railsupporting arm 81, whereby said arms 81 form horizontal guides for theejector slides and the caps as they are transferred from the conveyers16 to the supporting rails |0|, |03, as shown in Figure 2, and foranother purpose hereinafter set forth. The arms 81 superposed to theslides ||2, extend'over the inner ends of the slideways as at |35 inFigure 2, and have pins |36 projecting laterally from the opposite sidesfor the releasable engagement of hook portions of latches |31 pivotallymounted on the opposite sides of theslldeways and yieldingly maintainedin engagement with the pins |36 by springs |38 anchored at one end tothe hangers |3| and at the opposite'ends to the latches opposite to thehook portions thereof, as clearly shown in` Figc re '1.

The latches |31 when engaging the pins |36 retain the guide rails 86 andarms 81 in their normal guiding position. It will be noted that theejector slides are only reciprocated when drive shaft 4I1 is connectedto the drive wheel 20 and the independent operation of the capdelivering conveyers 55 and 16 from the drive wheel will not cause anytrouble as the conveyers 16 will merely travel relative to the capswithout transporting the caps when the i portions of said conveyers 16between the conveyor 55 and abutments |08 are lled with caps ready to betransferred to the supporting rails |0|, V|03 by theslides ||2 upon theactuation of said slides.

The sprocket chain |22 and sprocket wheels |23 and |24 are enclosed'by aprotective shield |39 supported by the hangers I9 and |2|, as at |40 inFigure 1, to prevent accumulation of dirt on said operating parts andinjury to the operator.

The caps C transferred from conveyers 16 to the supporting rails |0|,|03 by ejector slides ||2 y are positioned relative to means forintermittently moving the caps along the supporting rails in positionrelative to the assembling devices, and comprises projections or:fingers |4| xed in spaced relation to each other and extendedvertically from the links of a pair of sprocket chains |42 extending inalinement with the slots I 04 with the fingers projecting therethrough,and engaged about pairs ,of laterally spaced sprocket wheels |43, |44the sprocket wheels |43 being looselyV mounted in separate rectangularbrackets |45 having a side portion of channel form, as at |46 in Figure7, to slidably engage longitudinally extending blocks |41 xedlysupported below the bed B, two of said blocks extending along themarginal portions of the bed and a third block intermediate said twoblocks, whereby each sprocket wheel |43 may be independently adjustedlongitudinally of the bed to take up slackin the chains by set screws|48Y threaded into ears |40 extending laterally of each bracket so thatthe inner ends of the set screws abut the ends of the outer blocks |41and move the bracket toward the adjacent end of the bed B. 'Ihe brackets|45 are retained in adjusted position by clamping screws |50 engaged inthe lower channel wall of the outer channeled sides of the brackets |45and the outer blocks |41, and a T shaped clamping member |5| engagedbetween the opposed channeled sides of the brackets with the T portionthereof clamped against said channeled sides by a screw similar toscrews 50. The other pair of sprocket wheels |44 comprises the drivingmeans for said cap feeding chains and are releasably and adjustablymounted on a shaft |52 (Figure 3) rotatably mounted in brackets |53 xedto the opposite sides of the bed B at the end thereof opposite to theend arranged with the conveyers 55 and 16, and intermittently actuatedfrom a continuously rotating shaft |54 rotatably carried by saidbrackets |53 below shaft |52 through a Geneva mechanism (Figures 3, 15and 16), comprising a disk' |55 fixed on an end of the shaft |52extended beyond a bracket |53 and having recesses|56 equidistantlyspaced about and extended radially inward from the periphery with theperipheral portions of the disk between the recesses of curved orconcave form, as at |51, for the engagement of convex surfaces at theoppositel ends of an elongated block |58 xed axially of a disk |59mounted on an end of shaft |54 extending beyond a bracket |53, saidengagement being for the purpose of holding disk |55 in such position.The disk |59 has rollers |60 mounted on pins |6| fixed in and projectingfrom the disk adjacent the periphery and at diametrically opposite sidesof the block |58,v so that the rollers by the rotation of the shaft |54will engage the recesses |56 and impart two intermittent movements tothe disk |55 and shaft |52 upon each revolution of shaft |54.

'Ihe shaft |54 is continuously and simultaneously rotated with theactuation of the cap trans-A ferring slides ||2 and the assemblingdevices by a pair of sprocket chains |15 engaged about a wheel |16having a double row of sprocket teeth and xed on the end of shaft 54opposite to the disk |53, and a wheel |11 having a -doublerow ofsprocket teeth and fixed `to an end of a crank shaft |18, similar to thedrive shaft I1, mounted below the bed B in spaced relation to the shaft|1 and driven from said drive shaft through a pair of sprocket chains|19 engaged over wheels |80 having a double row of sprocket teeth xed onthe ends of shafts I1 and |18 opposite tothe drive wheel 20 and sprocketwheel |11, respectively. The sprocket chains |15 and sprocket wheels|16, |11 are enclosed by a sheet metal cover |8| and the sprocket chains|19 and sprocket wheels |80 are also enclosed by a cover |82 mounted onthe -eo supporting structure.

The fingers |4| of one chain may be adjusted independently of andrelative to the fingers of the other chain for the purpose ofaccommodating the apparatus for different sizes of closure caps and toposition caps of different sizes in alinement with the sealing pad or`lining assembling devices to assure proper assembling of sealing padsand linings in the closure caps. This adjustment is accomplished in asimple and rapid manner by adjustably mounting the sprocket wheels |44on the shaft |52 by cup members |62 (Figure 16) fixed on the shaft |52with the open ends in opposed and spaced relation to each other, the cupmembers' having a sleeve-like hub portion |63 with the free |4| alongtheslots |04 and feed. the caps enends thereof externally screwthreaded. The sprocket wheels |44 are nxed to a flange of sleeves |64loosely engaged on the hub portions |63 and adjustably connected withthe cup members through worm wheels |66 fixed on the sleeves |64 meshingwith worms |61, rotatably mounted in the walls of the cup members |62 toextend transversely of a peripheral open portion |66 of vsaid members topermit ready actuation of the worms by a tool applied to squared ends|69 of the worm shafts exterior of the-cup members. By rotating theworms the sprocket wheels |44 are adjusted about the `shaft |52 to anypredetermined position to properly position the cap engaging fingers |4|along the supporting rails |0|, |03, and relative The sprocket wheels tothe assembling devices. '|44 are releasably secured in adjusted positionto permit the intermittent actuation of the chains '|42 by plates |10loosely engaged on the hub portions |63 of the cup members andperipheral- Y'ly flanged to'correspond'with the edges -of the cupmembers, as at I1 and clamping the sprocket wheels to the cup'members byannular nuts |12 threaded .onto the screw threaded end of the hubportions |63, Vsaid nuts having' a series of sockets |13 about theexterior walls for the engagement of a spanner wrench to tighten thenuts against the plates and impinge the sprocket wheels to the cupmembers, When it is desired to -assemble sealing pads or lining disks incaps of asize different than the caps being assembled, .the nuts |12 areloosened to release the plates |10 and permit the adjusting of thesprocket wheels |44 to the desired position about the shaft |52 -bytheactuation of the worms |61.

The Geneva mechanism .comprising the disks |55 and |59 is protected fromdirt accumulating thereon by an enclosure |14 formed of separablesections, as clearly disclosed in Figure 15,- sup-f. ported by a bracket|53.

The c ap engaging fingers |4| are of T form fixed at the bottom or footportions thereof to angle portions of angle members |83, the other angleportions constituting links of the chains |42, as clearly shown inFigure l5, with the leg portions of the 'fingers extending through theslots |04 while the chains are traveling relative to said slots with`the cross portions of the fingers above the supporting rails |0I, |03presenting broad cap engaging surfaces and assuring positive engagementlwith the caps.

The reciprocation of the ejector slides ||2 and the intermittentmovement of the shaft |52 are synchronized so that during the movementof said slides away from the supporting rails |0|, |03, saidshaft willbe rotatedto move the fingers lgaged by said fingers along thesupporting rails, and during the, actuation of the ejector slides topositionja cap on the supporting rails the Ashaft |52 will be idle withfingers |4| positioned on. both sides of the advancing ejector slides toV'form spacesinto which the -caps being transferred from the conveyers16 are positioned by the ejector slides and moved along the supportingrails upon the next rotation of the shaft |52. The caps areintermittently moved by the fingers |4| along the supporting rails fromthe ejector slides to a series of devices adapted to asplate openings byscrews |94.

'linings superposed to the pads to protect the pads from thedeteriorating action of the con- 10 tents of the receptacles to whichthe caps vare applied. A pair of punch and die mechanisms comprises apair of slides |64 movably mounted in vertical slideways arranged instandards supported on 15 and extended upwardly from the opposite sidesof the bed-B, the slides beingreciprocatedfrom either the drive shaft |1or shaft |18, depending upon the location of the punch andvdiemechanisms, through a pair of crank arms |86 2o 'at one end looselyengaged on the crank portions |8 of vsaid shafts with the opposite endsloosely engaged'on a shaft |81, the ends of which l*shaft extendlaterally from the crank arms and rotatably engage `openings in thelower endsof 25 the slides |84 retained on the' shaft by nuts, as

at 301,'the slides passing through openings |86 in the bed B, as clearlyshown in Figure l8. The intermediate portions of the slides |84 arearranged with alined rectangular openingsl |89, 3o'

for apurpose to lbe hereinafter described. vOn the upper ends of theslides there is supported v a plate |90 releasably connected thereto byscrews' |9| The plate |90 has a pairof circular openings, each openingbeing adjacent the opposite 35 sides' and ends of the plate, andtherefore, di-

agonally opposed 'to each other to be engaged by bushings |92 having aflange |93 abutting the upper surface ofthe plate and secured in the Thebushings |92 4o carry tubular members |95 retained therein by nuts |96threaded on end portions of the tubular members extended above thebushing flanges |93 to abut washers |91 against the under surfaceof'the` plate |90, said washers being 45 retained in abutting positionby nuts |96 threaded onto the tubular members below the plate |90. Bythis mounting of the tubular members, the members may have longitudinaladjustment in the plate |90. The tubular mem- 50.

bers |95 carry at the lower ends cup shaped punches or cutting heads |88having tubular portions to be attached to the tubular members, as byscrew threading, as shown at l200 in Figures 8 and 10. The edges at theopen ends of the 55 'punches are beveled to fonn cutting edges toco-operate with annular dies 20| mounted in seatsinjopenings 202 in aplate 203. The plate' 203 is. releasably mounted on the sill portions ofopenings 204 inthe standards |85 by screws 60 engaged in openings inplate 203 with the heads countersunk therein, as shown at 205 in Figure8'. The sealing pads or linings are severed by the punches and dies froma web W of suitable material fed through'the openings lss of the. slidese5 |64 and openings 204 in the standards |65 over the die plate 203 ininterposed relation between To assure the severing of the pads orlinings with a clear cut edge,

the webV about the peripheres of the dies are 70 engaged and heldagainst a beveled portion of the diesextended above the plate203, as at206. by a corresponding beveled edge of holding members of cup form 201slidably mounted to encircle the cutting heads lss with the beve1ea nsedge projecting beyond the heads by rods 209 fixed at one end in theholding members and slidably engaged in perforations circumferentiallyarranged in rings 209 engaged on the tubular members |95 below shoulders2I0 on said tubular members, the holding members being yieldinglymaintained in position with the beveled edge extending beyond thecutting edge of the heads by springs 2|| coiled about the rods betweenthe holding members and the rings 209, whereby the beveled edge willclamp the web against the beveled edge 206 of the dies and maintain theweb in such position during the severing of the web by the cutting headsor punches, the tubular punch carrier |95 passing through an opening 2|2 in the bottom of the holding members 201 against the force of thesprings 2| I, as shown in Figure 10.

To assure the positioning or assembling of the pads or linings centrallyin caps positioned below the openings 202 in plate 203, the pads orlinings immediately after being severed by the cutting heads |99 areengaged in the caps and stripped from the cutting heads by plungerscomprising a. rod 2 I3 slidably mounted in the bore of the tubularmembers |95 with the upper end extending above plate and engaged bycoiled springs 2I4 compressed between the tubular members and bifurcatedmembers 2|5 pivoted to the said projecting end of the rods whereby heads2|6 at the lower end of the rods having an inclined lateral wall areyieldingly maintained within the cutting heads |99, the inclined wallcoinciding with the cutting face of said heads, as shown in Figure 8.After the cutting heads have passed the dies 20| and severed pads orlinings from the web W the plunger heads 2|8 are positively and forciblyactuated out of the cutting heads to strip the severed pads or liningsfrom the cutting heads and position the severed pads or liningscentrally in the caps by levers 2| 1 pivoted intermediate their ends inbifurcations 2|8 in the upper end of posts 2|9 fixed in the plate |90adjacent the punch mounting, as by screw threading as shown in Figure 8,one end ofthe levers 2|1 loosely engaging the bifurcated members 2|5carrying rods 2I3 below pins 220 fixed in said bifurcation legs toextend transversely of the levers to permit of longitudinal movement ofthe levers 2 |1 relative to the plunger rods 2I3 and the opposite endsof said levers engaging rollers 22| loosely carried by brackets 222adjustably mounted on the upper endsA of the standards |85, as by ascrew and slot connection 223, to vary the movement of the levers.

The' abutting of the levers with the rollers by the downward movement ofthe slides |84 will rock they levers and move the plunger -rods 2I3 in afdownward direction against the force of the springs 2'I4 and actuatethe yplunger heads 2I6 out of the cutting heads |99, thereby strippingand engaging the pads or linings in the caps, as shown in Figure 10.During the return upward movement of theslides l|84 the web holdingmembers 201 will assume their position about the cutting heads |99 underthe influence of springs 2| I, and the plunger heads 2IB will assumetheir normal position within the cutting heads |99 under the influenceof springs 2I4.

By the mounting of the punches and dies as hereinbefore described, theymay readily be replaced by punches and dies of different diameters tosever pads or linings for caps of diierent sizes, b y simply removingthe retaining screws I9l, 205 for the plates |90 and 203, re-

spectively, and permit the removal and replacement of said plates |90and 203.

'I'he opposed standards |85 arranged with the slideways for the slides|84 are maintained in uniform spaced relation by spacing members in 5the form of rods 224 having the opposite ends reduced in diameter andengaged in perforations in ears 225 projecting from the top of standards|85, an end of one of said rods being extended beyond an ear for looselymounting thereon the 10 manipulating lever 5| for the clutch and brakemechanism of the drive shaft I1, as at 226 in Figures 1 and 2.

The crank portions I8 of the shaft I1 and similar crank portions of theshaft I18-are arranged 15 in relation to the Geneva actuating mechanismfor the chains |42, so that the punches |99 will sever and position thepads or linings in the caps during the` periods of rest of the chains,and during the actuation of the chains the slides |84 20 will move thepunches out of severing position, as shown in Figure 8.

A single web W of suitable pad or lining matey rial-is fedsimultaneously to each pair of punch and die mechanisms and is of awidth substan- 25 tially equal to the width of the plates |90, 203 andsuilicient to permit the severing of two parallel rows of pads orlinings lfrom said webs, as shown in the waste portion of web at U inFigure 8, and whereby the maximum amount of 30 the material of the webis utilized in the forming of pads or linings. l

The web W is fed over the die plate 203 of each pair of punch and diemechanisms between a pair of guide flanges 221 extended above the faceof 35 the plate at the opposite sides thereof, by a. pair of superposedfeed rollers 228, 229, the lower roller 229 being fixed on a shaft 230rotatably supported in a pair of opposed brackets 23| fixed to the sideof the bed B, as clearly shown in Fig- 4o ure 8, and the upper roller228 being supported by a shaft 232 engaged at the opposite ends inblocks 233 slidably mounted in opposed slideways 234 extended upwardlyfrom the brackets 23|. The roller 228 is yieldingly urged into engage-45 ment with roller 229 to feed the web toward the punch and diemechanisms by coiled springs 235 engaging at one end protuberances 236extended from the blocks 233 with the opposite ends coiled about andabutting annular enlargements 231 of 50 set screws 238 adjustablymounted in cap members 239 secured to and extended transversely of thetop of the slideways 234, whereby the tension of the springs and theforce of engagement facilitate the engaging or threading of the web`/between the feed rollers, roller 228 is readily positioned away fromthe roller 229 against the tension of springs 235 by arms 240 looselymounted on the shaft 232 at the opposite ends of the roll- 60 er 228 andarranged with ears extending centrally from the lower ends thereofcarrying rollers, as shown at 24| in Figures 8 and 9, to engagehorizontal recesses at the lower ends of the slideways 234, one end ofthe recesses extending into a side 66 of the slideways, as at 242, whichend the rollers 24| engage when the feeding rollers 228, 229 are inengagement with each other under the iniluence of the springs 235, asshown in Figure 8. When it is desired to adjust the roller 228 away 70from roller .229, the arms 240 are moved about the shaft 232 intovertical allnement with the slideways 234 positioning the rollers 24| inthe horizontal recesses in alinement with the axes of the rollers 228,229, said position of the rollers 75 24| moving the roller 228 away fromroller 228,

asshownin Figure 9. To facilitate the simultaneous actuation of the arms248 of each pair of rollers to their adjusted positions. the upper endsof the arm are arrangedwith manipulating means in the form of a crosspiece attached at the opposite ends to the upper vends of each pair ofarms and havingan elongated opening therein, as clearly shown at 248 inFigures 2 and 3,

To for the ready engagement of the fingers of the hand of the operatorof the apparatus.

The rollers 228, 229 are intermittently rotated during the travel of thecap feeding chains |42 'and with the punches in spaced relation to thedies to feed successive predetermined lengths of the web to the punchand diemechanisms to be severed into pads or linings, by gears 244 fixedon projecting ends `of the shafts 238, 232 'of said rollers meshing witheach other to positively drive roller 228 fromroller 228, the shaft 238of roller,

229 being intermittently rotated through'an overriding clutch mechanism(Figure .11), comprising a disk 246` xed on the end of shaft `238opposite the end carrying the gear 244 and having a series ofequidistantly spaced wedge shaped recesses about the periphery thereofto form tapered chambers `246 with ,the ilange of a cup shaped member241 loosely mounted on the shaft 238, for the freeengagement of balls248 yield- 30 ingly urged toward the reduced ends of said chambers 246by springs 248 conned between the balls and the `opposite ends of'thechambers. whereby movement of thev cup'member toward v,the punch and diemechanisms or in an anticlockwise direction, looking 'at Figure 11, will1 through friction impinge the balls 248 between the flange and the diskand impart rotation to the diskandlshaft 238 in the same direction.Movement of the cup -member 241 in clockwise direc- I o tion willactuate the balls against the force of the y 50 ment 264 on theend ofthe shaft at the outer -side of the clutch mechanism, as shown in Figure11,the periphery of said disk being engaged by a split ring 266 havingalateral projection 268 plvotally connected to a bracket 261v fixed tothe bed 55 .B, the split ends of the ring having lateral ears 268 withone ear carrying a stud 268 passing through a perforation in thev otherear with the portion thereof extending.' beyond said other ear engagedbya coiled spring 218` adjustably com- 50 pressed against said other earby a nut threaded vonto the free end of the stud, whereby the ears areyieldingly forced. together but may be separated by the rotation of theshaft 238 in anticlockwise direction. as viewed in Figure 11, to

05 Apermit rotation` of the shaft by the movement of the cup member 241in said direction.

, 'I'he cup member 241 is actuated inthe opposite directions by a blockv268 slidably mounted in a slideway arranged at Aone side of thebrackets 70 523|, as at 25| inFigures 2 and 3, carrying a rack bar 262meshing with a pinion 263 fixed to the4 cup member, the slide blockbeingv reciprocated by van actuator slide 264 slidable in the slideway26| at the outer end of the slide block 268 and 75 a pin andslot'connection 266 with an arm 266 xed to an end of a shaft`261journaled in hangers 268 extended from the brackets 23| (Figures l and8) `with an arm 268 fixed to the shaft 261 between the hangers 268pivotally carrying a bifurcated member 268 pivotally connected to 6 oneend of a crank arm 28| pivoted at the opposite end to acoilar 262 looseon a plntle 21| adjustably mounted on a lead screw 212 rotatable inavbifurcationl of a block 213 fixed concentrically to the sprocket wheel|88, whereby v the l0. movement of the crank arm may be varied andthereby vary the length of web fed to the punch vand diemechanisms forthe purpose of severing different size pads or linings. l

The slide block 268 is releasably connected to l5 the actuator slide 264to participate in the reciprocations of the actuator slide through-alatch 214 pivotally mounted at one end between a pair of ears 216extended from the outer end of the slide block juxtaposed to theactuator slide vwhen 20.

the slide blockis coupled with the actuator slide, as shown in Figurel1, the free end of the latch being of hook form to engage the outer endof the actuator slide by gravity. To prevent the feeding of the web tothe punch and vdie mechanisms 25l should there be'no caps positioned oneither pair of cap supporting rails |8|, |83, to be moved by the chainfingers |4| to position in aiinement with thepunch and die mechanismsduring the feeding of the web, and thereby prevent the waste of web thatwould be severed if the web was fed without a cap being positioned toreceive the severed web portion, the latch 214 is normally positionedout of engagementv with and uncoupled from the actuator slide bya slide216 mounted in a vertica1'35 l slideway formed by a plate 211 xed to andcovering a recess in the exterior of the slideway 26|,

vin whichl recess the slide is engaged, as shown in Figures 2, 3 and 8,to engage a bar 218 fixed to and extending transversely ofthe latch withya 40 portionextended -into the path of movement of the slide 216. Theslide 216 is normally urged upwardly to engage the bar 218 and positionthe latch out of lengagement with the actuator slide 264 and uncouplethe slide block 268 from the 45 actuator slide, by a pair of levers 218,288 having ear portions at one end for the engagement of set screws 28|threaded into a lateral extension 282 of the slide 216 projectingthrough a slot :as 1n the ende piete 211 extending from the bot- 50 tomedge to adjacent the upper edge thereof to limit upward movement of theslide. The end of lever 219 opposite the ear is fixed on a shaft 284rotatably supported at one end in one'of the brackets 23| (Figure 1) andengaged in a hollow 55 shaft 285 rotatably supported at the end oppositeto the end at which the shaft 284 is supported in the one bracket I23|by the other bracket 23| with the ends of the shafts extending beyondsaid bracket, and said end or the shaft zu. projecting beyond the shaft285, with cranks 286 xed on l said extending ends, as clearly shown inFigures '1, 12 and 13. `The lever 288 lis fixed on the hollow shaft 285in juxtaposed relation to the ,lever 218, the ear portions of bothlevers being yieldingly urged upward to engage the set screws 28| andactuate the slide 216 by springs 281 attached at the opposite ends tothecranks 286 and a pin 288 ilxed in andextended from the standard |86, asshowninFigurel.

The ear portions of levers 218, 288 arepositively actuated away from theset screws 28| independently of each other to permit the slide 216 tomove downwardly by gravity and the hook portion of the latch 214 toengage the actuating slide 25d, but it will be noted that both leversmust be actuated in a downward direction before the latch 218 engagesthe actuating slide, lso as to prevent the feeding of the predeterminedlength of web and the waste of even a single pad or lining should therebe only one cap Abelow the punch and die mechanism instead' of the usualtwo caps. The levers 219, 280 are actuated through shafts 299, 285 byarms 289, 290 pivotally mounted on the outer guide rails |05, arm 289being pivoted at one end and connected to the crank 286 xed on hollowshaft 285 by a rod 29| having a block 292 at one end pivotally connectedto the crank 20S and having one end of spring 281 anchored thereon, asshown in Figures 12 and 13, the opposite end of rod 29| being adjustablyconnected to a vertical projection 293 fixed to the face andintermediate the ends of arm 289, so that the length of the rod betweenthe crank 286 and projection 293 may be varied to vary movement of thelever 280. The arm 290 is pivoted intermediate its ends and connected tothe crank 28S on shaft 289 by a rod 290 having a block at one endsimilar to the block 292 pivoted to the crank 286 and adjustablyconnected at the opposite end to a projection similar to projection 293but iixed to the arm 290 adjacent one end thereof to facilitate themounting of the arms 289, 290 in opposed relation to each other, asclearly shown in Figures l2 and 13. The free ends of the arms 289, 290are arranged with fingers 295 of greater thickness than the arms andfixed in juxtaposed relation to the undersurface of the arms to bepositioned in elongated recesses 296 in the outer guide rails |05corresponding in size and shape to the lingers, whereby the outer sidesof the fingers will be flush with the guiding edges of the rails|05`when the fingers are fully engaged in said recesses. The arms 289,290 are normally actuated by the springs 231 to position the fingers 295out of the recesses 299 and in the path of travel of the caps beingtransported by the chains |82 to the punch and die mechanisms, the capsrst engaging the portions of the iingers nearest the pivots of the armsand during their travel to the punch and die mechanisms progressivelymove the fingers into the recesses 296. The chains are synchronouslyactuated to position the caps during the periods of rest of said chainswhere the caps will engage the fingers 295 fully within the recesses296, as shown in Figures 12 and 13, in which p0- sition of the arms 289,290, the levers 219, 280

will be positioned away from the set screws 28|,

thereby permitting the latch 218 to engage the actuator slide 254 andcouple said slide to the slide block 250, and the feeding of a predeter`mined length of web to the punch and die mechanisms to be severed intopads or linings and said pads or-linings being assembled in the capsthat are in engagement with and have actuated the fingers 295. Shouldthere be no cap on either one of the pairs of cap supporting rails, asillustrated in Figure 13, the web will not be fed to the punch and diemechanisms as the lever 219 by the position of arm 290 will maintain theslide 216 in engagement with the latch 214 and said latch in elevatedposition out of engagement with the actuator slide.

It will be noted from Figures 2 and 3 that the cap engaging fingers |4|of one chain |42 are not in alinement with the fingers of the otherchain but are in staggered relation to each other'to properly positionthe caps in alinement with the respective punch and die mechanisms, andthe fingers of each chain are properly adjusted relative to each otherby loosening the plates |10 and adjusting the worms |61 carried by thechain actuating shaft |52, as hereinbefore set forth. The staggeredarrangement of the fingers 4| is another reason why the cap transferringslides 5 2 are offset relative to each other, as shown in Figure 2, toproperly position the caps relative to the ngers IM.

To maintain the caps in alinement with the punches and dies during theassembling of the 10 linings therein, said caps are yieldingly engagedby jaws in the form of rectangular blocks (Figure l2) having a V-shapedcut out in one side thereof, as at 291, with ears 298 extended from theopposite ends at the side of the blocks opposite the V-shaped cut outadapted to slidably engage the ends of rectangular recesses 299 in theouter cap guide rails |05 in alinement with the respective punch and dieof each pair of punch and die mechanisms, said recesses having at theentrances thereto inwardly extending projections 300 corresponding tothe Aears 298 and normally engaged by said ears by springs 30| confinedbetween the jaw blocks and the bottom of the recesses with the V sidesof the blocks projecting into the .path of travel of the caps to thepunch and die mechanisms, the forward movement of the caps moving thejaw blocks into the recesses 299 and in the position of the caps inalinement with the punch and die mechanisms the V face of the blockswill engage and impinge the caps against the center guide rail |01 underthe iniiuence of the springs 30|. The ears 298 and projections 300 limitthe outwardmovement of the jaw blocks into the path of travel of thecaps so that the blocks will not impede the travel of the caps along therails |01, |03.

The webs W travel from the rolls of said webs, not shown, to the feedingrollers in a plane substantially level with the bits of the rollers tofacilitate the feeding of the webs and prevent breakage thereof byguiding the webs between a pair of vertical rails 302 adjustably mountedin slots 303 extended transversely of plates 309 secured to one side ofthe slideways 25|, as shown 45 in Figures 2 and 3, and upon which platesthe webs are supported. The webs are maintained upon the supportingplates 304 in alinement with the bits of the rollers by rods 305 carriedat the outer ends of the rails 302 to extend transversely of the platesabove the webs, as shown in Figure 1. By the mounting of the rails 302on the plates 399 the rails may be adjusted toward or away from eachother to permit the feeding of webs of diierent Widths for severing padsor linings of different sizes with a minimum of waste of the web. Thelengths of the rollers 228, 229 are suiicient to feed webs for pads orlinings of maximum size the apparatus is capable of assembling, andtherefore, they need not be changed when the apparatus is adjusted fordifferent size caps, as hereinbefore described relative to the differentdevices of the apparatus.

After the sealing pads are assembled in the caps by the first pair ofpunch and die mechanisms shown in Figure'2, they are intermittently fedand positioned relative to the second pair of punch and die mechanismsshown in Figure 3, where another sealing pad of ordinary absorbentmaterial may be severed and assembled in the caps but usually a web ofpaper having a varnished surface is fedto the second pair of punch anddie mechanisms for the assembling of impervious linings superposed tothe sealing pads to protect the pads and the caps from the deterioratingac- 76 vthe other by not feeding a Web to the pair of punch and diemechanisms to be rendered inoperative, by adjusting the pintle 21| onthe lead screw 212 in alinement with the shaft Il or |18, whereby noreciprocatory movement will be imparted to the actuator slide 254 andthe web feeding rollers 228, 229 will not be actuated, or no web may beengaged between the rollers 228, 229 to be fed by said rollers to thepunch and die mechanisms. I

'Ihe waste portions U of the webs W are guided and supported from theside of the .apparatus opposite to the side arranged with the webfeeding rollers 228, 229, by chutes 308 mounted on the standard |85 withthe upper ends flush with the web supporting surfaces of the die plates203, so that the webs will lie flat on said plates 203 and assure theproper severing of the webs.

After the impervious linings have been assembled in the caps, the capsare intermittently moved along the cap supporting rails l I, |03, awayfrom the second pair of punch and die mechanisms by the chains |42 untilthey reach a point slightly .beyond the shafts |52, |54, Where thechains travel about the sprocket wheels |44 on the shaft |52, and fromsaid point to the adjacent ends of the rails |0|, |03 the caps are movedtoward said ends and discharged from the rails by the continued movementof the subsequent caps by the chains |42l along the rails. The caps aredelivered from the rails to a chute 306 declining from the end of therails to a suitable depository, not shown.
